UCI design for UL transmission with configured grant

Abstract

Methods and apparatuses are described herein for uplink control information (UCI) design for uplink (UL) transmission with configured grants. In accordance with one embodiment, a wireless communications device may receive, from a gNB, first information indicating a plurality of resources for a configured grant (CG) on a physical uplink shared channel (PUSCH). The wireless communications device may determine, based on second information, a portion of the plurality of resources to use for transmitting a configured grant-uplink control information (CG-UCI). The wireless communications device may generate the CG-UCI, wherein the CG-UCI comprises at least one of: an identifier associated with the wireless communications device or an indication of a modulation and coding scheme (MCS). The wireless communications device may transmit, to the gNB on the PUSCH, the CG-UCI using the determined portion of the plurality of resources.

What is claimed is: 
     
       1. A wireless communications device comprising a processor and a memory, the wireless communications device further including computer-executable instructions stored in the memory of the wireless communications device which, when executed by the processor of the wireless communications device, cause the wireless communications device to:
 receive, from a gNB, first information indicating a plurality of resources for a configured grant (CG) on a physical uplink shared channel (PUSCH); 
 determine, based on second information, a portion of the plurality of resources to use for transmitting a configured grant-uplink control information (CG-UCI), wherein the second information comprises a radio resource control (RRC) parameter enabling the wireless communications device to calculate a number of symbols or resource elements to use for transmitting the CG-UCL, the RRC parameter comprising CG-UCI signature corresponding to an offset value dedicated to the CG-UCI; and 
 transmit, to the gNB on the PUSCH, the CG-UCI using the determined portion of the plurality of resources, wherein the determined portion of the plurality of resources comprises symbols mapping the CG-UCI first and then a hybrid automatic repeat request (HARQ) acknowledgement (ACK), and wherein the symbols are generated using the CG-UCI signature. 
 
     
     
       2. The wireless communications device of  claim 1 , wherein the determined portion of the plurality of resources comprises symbols following symbols carrying a demodulation reference signal. 
     
     
       3. The wireless communications device of  claim 1 , wherein the CG-UCI is attached with cyclic redundancy check parity bits. 
     
     
       4. The wireless communications device of  claim 1 , wherein the second information is configured via RRC signaling. 
     
     
       5. The wireless communications device of  claim 1 , wherein the second information is based on a predetermined configuration. 
     
     
       6. The wireless communications device of  claim 1 , wherein the computer-executable instructions, when executed by the processor of the wireless communications device, further cause the wireless communications device to:
 generate the CG-UCI, wherein the CG-UCI comprises at least one of: an identifier associated with the wireless communications device or an indication of a modulation and coding scheme (MCS). 
 
     
     
       7. A method for use in a wireless communication device, comprising:
 receiving, from a gNB, first information indicating a plurality of resources for a configured grant (CG) on a physical uplink shared channel (PUSCH); 
 determining, based on second information, a portion of the plurality of resources to use for transmitting a configured grant-uplink control information (CG-UCI), wherein the second information comprises a radio resource control (RRC) parameter enabling the wireless communications device to calculate a number of symbols or resource elements to use for transmitting the CG-UCI, the RRC parameter comprising CG-UCI signature corresponding to an offset value dedicated to the CG-UCI; and 
 transmitting, to the gNB on the PUSCH, the CG-UCI using the determined portion of the plurality of resources, wherein the determined portion of the plurality of resources comprises symbols mapping the CG-UCI first and then a hybrid automatic repeat request (HARQ) acknowledgement (ACK), and wherein the symbols are generated using the CG-UCI signature. 
 
     
     
       8. The method of  claim 7 , wherein the determined portion of the plurality of resources comprises symbols following symbols carrying a demodulation reference signal or symbols preceding symbols carrying a demodulation reference signal. 
     
     
       9. The method of  claim 7 , wherein the CG-UCI is attached with cyclic redundancy check parity bits. 
     
     
       10. The method of  claim 7 , wherein the second information is configured via RRC signaling. 
     
     
       11. The method of  claim 7 , wherein the second information is based on a predetermined configuration. 
     
     
       12. The method of  claim 7 , further comprising:
 generating the CG-UCI wherein the CG-UCI comprises at least one of: an identifier associated with the wireless communications device or an indication of a modulation and coding scheme (MICS). 
 
     
     
       13. A method for use in a network node in a wireless communication system, the method comprising:
 transmitting, to a user equipment (UE), first information indicating a plurality of resources for a configured grant (CG) on a physical uplink shared channel (PUSCH); and 
 receiving, from the UE on the PUSCH, a configured grant-uplink control information (CG-UCI) using a first portion of the plurality of resources, 
 wherein the first portion of the plurality of resources is determined based on second information comprising a radio resource control (RRC) parameter enabling the UE to calculate a number of symbols or resource elements to use for transmitting the CG-UCI, the RRC parameter comprising CG-UCI signature corresponding to an offset value dedicated to the CG-UCI, and 
 wherein the determined portion of the plurality of resources comprises symbols mapping the CG-UCI first and then a hybrid automatic repeat request (HARQ) acknowledgement (ACK), and wherein the symbols are generated using the CG-UCI signature. 
 
     
     
       14. The method of  claim 13 , wherein the determined portion of the plurality of resources comprises symbols following symbols carrying a demodulation reference signal.
